08053A390KAT2A

The AVX 08053A390KAT2A is a multilayer ceramic capacitor (MLCC) in the 0805 surface-mount package format. This component belongs to the general-purpose ceramic capacitor family and is designed for use in a wide range of electronic circuits requiring reliable energy storage, filtering, and signal coupling functions. MLCCs like this part are among the most widely used passive components in modern electronics. The 0805 package represents a standard size in surface-mount technology, measuring 2.0mm by 1.25mm, making it suitable for both high-volume automated assembly and space-constrained designs. This package size offers a practical balance between compact footprint and handling ease on manufacturing lines. Multilayer ceramic capacitors function by stacking alternating layers of ceramic dielectric material with internal metallic electrodes. This construction enables high capacitance values in small physical sizes while maintaining relatively low cost. The capacitive performance makes these components ideal for decoupling and bypass applications, where they suppress voltage ripple and noise on power distribution networks. They are also commonly used in signal conditioning circuits, coupling networks, and frequency-selective applications across consumer, industrial, and automotive electronics. The AVX brand represents a manufacturer with strong reputation for consistent quality and reliability in the capacitor market. AVX MLCCs are specified across diverse industries including telecommunications, computing, power management, and industrial control systems. Engineers typically select specific MLCC part numbers based on required capacitance value, voltage rating, temperature stability characteristics, and package size constraints. The designation within this part number indicates specific electrical properties selected for particular circuit requirements. Engineers choose this exact part when their design calls for the specific capacitance value and electrical characteristics it provides, combined with the proven reliability of AVX manufacturing and the cost efficiency of high-volume MLCC production. Common reasons to specify a particular MLCC part number include matching exact capacitance tolerances needed for tuning circuits, selecting appropriate voltage derating margins for safety-critical applications, and matching temperature coefficients required by precision analog circuits. The 0805 package size remains popular in new designs despite the availability of smaller alternatives, as it provides good balance between miniaturization and assembly reliability. This component is suitable for engineers designing power supplies, signal processing circuits, digital logic boards, and mixed-signal systems where filtering and energy storage at the component level are essential to circuit performance and stability.
